ADDING-MACHINE.

Specification of Letters Patent.

Patented Apr. 21, 1914.

Application filed August 22, 1804. Serial No. 221,655.

In the construction of adding machines of the mutiple key-bank type,most machines are constructed in such manner that a number can bewritten of an order equal to the number of banks of keys. Where it isdesired, however, to print two or more columns of figures of low order,it has been customary to build what has become known as a split machine,in which case the keyboard, and mechanism controlled thereby, is dividedinto distinct sections which can have no effect one upon the other. Insuch machines, the construction has been practically mere duplicationwithout means of combination.

An object of my present invention is to provide a constructionby meansof which the recording of intermediate ciphers may be controlledwhereby, in one position of adjustment the means for recordingindividual items become unified into a complete and coacting structurewhile in the position of adjustment said recording means will beoperated as independent sections.

With a machine of the structure described, it is desirable that theaccumulating mechanism be under control, either automatically or by manually'manipulated means in such manner that any desired series ofnumbers may be accumulated for a total, while other series of numberswill have no effect upon the accumulating mechanism.

An object of my invention is, therefore, to provide means by which theaccumulating mechanism may be controlled, as to action or inaction.

The accompanying drawings illustrate my invention as applied to thattype of adding machines known as the Burroughs type, the fundamentalconstruction thereof being fully disclosed more particularly inBurroughs .Patents Nos. 504,963 and 505,078, issued on September 12,1893.

Referring to the drawings Figure 1 is a side elevation of such a machineembodying my invention, with the supporting frame shownin dotted lines;Fig. 2 is a vertical section on line 2 2 of Fig. 3 of the printing I 3section provided with an embodiment of my invention; Flg. 3 is a sectionon line 3 3' of Fig. 2; Fig. 4 a view similar to Fig. 2 with the partsin a difi'erent position of adjustment, and the section somewhat infront of the section plane of Fig. 2. Fig. 5 is a similar sectionshowing a modification of the combination and splitting means; Fig. 6ahorizontal section on line 6 6 of Fig. 5;

1, only showing means for automatically controlling the splitting andcombining mechanism by means of, a movement of the paper carriage; Fig.8 a rear elevation of the parts shown in Fig. 7 ;'and Fig. 9 is adetail.

It is to be understood that while I have shown my invention as appliedto an adding machine of the Burroughs type, such-illustrat-ion has beenmerely for convenience, and

that the invention is by no means to be limited to such a machine, meansand methods for adapting my invention to other types of calculatingmachines being readily apparent.

In the drawings, 291 indicates vertically reciprocable finger keys whichare arranged in the rows or banks of 9 each to indicate units, tens,hundreds, etc., to any desired ex tent. Each of these keys operates upona bell-crank lever 217 which in turn acts upon a locking slide 214which, when aotedupon, is held in the position to which it is moved by apawl 228. Each bell-crank lever 217 acts' upon a stop wire 270 which inturn controls the subsequent movement of mechanism for acting upon theadjacent wheel of the accumulator 916. The accumulator pinions arecarried by a swinging carriage 910 moved back and forth by a link 914having in its forward end an open notch 91 1 which engages the pin 910of the accumulator.

carriage 910. Link 914 is pivoted to the lower arm of the T lever 913which at the ends of its cross arm carries pins 913 and 913 adapted tobe engaged by the swinging pawl 821 carried at the end of a lever 813,said lever being carried by the shaft 800.' Link 914 is connected by alink 911 with the totaling key lever 227 and this key is connected by alink 226 with a lever 219 carrying a rod 202 adapted to act upon all oft e pawls '228 so as to simultaneously release the slides 214.

As is well known to those. familiar with a- Burroughs machine, theseries of accumulator pinions 916, one for each denomir ation, arearranged to mesh with a corre sponding series of sectors 610 carried atthe forward ends of the type-carrying levers or sector bars 611 alsocorresponding in number to the number of denominations or banks of ke s.The degree of movement or descent of t e sectors 610 and the consequentdegree of elevation of the rearward ortype bearin end of the levers 611,is dependent upon 51c particular sto wires 270 of each bank or row ofkeys w 'ch may have been operated. Upon the initial movement of thehandle or main operating shaft of the machine the accumulator pinions916 are thrown or swung forwardly out of mesh with their sectors 610 byreason of the action of the pitman or link 91 upon the accumu-.

lator carriage or frame 910, which pitman or link is at this timemovedforwardly'longitudinally by the anti-clockwise oscillation of the lever913 through the medium of the rockin lever 813 and 1ts pawl or wipeplate 821. ile the pinions are thus out of mesh, the sectors 610corresponding to the denominations where keys have been operated nowdescend distances dependent upon the values of the keys operated butupon the return stroke of the operating handle the pinions are restoredto mesh with their sectors by reason of the rearward movement of thepitman or link 91 1, with the result that the values of the keysoperated are transferred to the pinions upon the return movement of thesectors. When a grand total is taken the total key is .depressed withthe result that the bell crank 227 is rocked downwardly and the link 911is likewise de-' pressed, causing the latter to so shift the position ofthe link 914 as to interfere with its usual functions, whereby theaccumulator pinions are left iii-mesh with their sectors or racks 610which are permitted to descend distances dependent upon the values ofthe respective pinions and to thereby pe'rmit the printing mechanism toprint, as the total, the amount expressed by the accumulator pinions. Ifthe total key is kept de pressed throughout the full operation of thehandle the total is a grand total and the machine will be cleared whenthe handle returns to normal position but in case the total key isreleased and permitted 'to ascend or return to normal position at theend of the forward stroke of the operating handle, thetotal printed willbe a sub-total inasmuch as the sectors or racks 610 upon their ascentduring the return stroke of the handle will be in mesh with theaccumulator pinions and will restore the latter to the position of valueformerly occupied by them-before the sub-total was taken, that is to saythe racks 610 will re-transfer to the pinions the amounts which were bythe latter trans-.

printing of the der Z) of the detent 717,'Figs. 2 and 4. Each detent 717is provided as shown in Fig. 3,

with a heel portion d and, with'the exception of the detentcorresponding to the units bank of keys, and also of such otherintermediate banks of keys as may be desired, each ofsaid detents isprovided with a bent tail portion d which overlaps the heel portion(Po-f the adjacent trigger representing the next lower order of value.Each detent 717 is also provided with a shoulder b adapted to be engagedby one of a series of pawls 718, each of which is provided with a tailadapted to be brought into engagement with a shoulder y formed upon thelower edge of the carrier 611, Figs. 2 and 4. The, pawls 718 are pivotedupon a shaft 7 04 carried by a pair of arms 711. When a complete machineis desired, 2'. 6., one in which the operation of any key in any bankwill cause the operation of the hammer 715 belonging to that bank, andalso the hammers belonging to all of the lower banks, 2'. e,

sired, 2'. 6., one in which the recording mechansm is divided into twoor more distinctsections, the operation of the keys in thecorrespondingsection not affecting in any manner the printing mechanism directlyrelating to another section, it has heretofore been customary to-omitthe bent tail'cZ of every detent relating to the right hand bank of eachset of banks, thus preventing transmission from one set of detents tothe other. 1 In the embodiment of my invention illustrated in thedrawings, I have shown two difierent means by which the machine can bemade either split or complete by providing mechanism which may be throwninto or out of action to serve as a transmitting element between thetwo. sets of detents. In Figs. 2, 3, 4: and 7 this mechanism consists ofthe following parts: Instead of the usual pawl 718 relating to the firstor lefthand bank of the right-hand Set of banks in the machine Isubstitute therefor an exactly similar pawl 71.8 which differs from theother merely in thickness. Arranged alongside of the pawl 718 is a pawl718 of substantially the same thickness and having its forward end ofthe same shape as the pawls 718 and 718, adapted to engage the shoulderb of theadjacent detent 717. The pawl 718 differs from the pawl 718 and718 in that instead of being provided at its rear end with an upturnedportion adapted to engage the shoulder o of an adjacent carrier 611, itis provided with a down-turned portion which carries a pin 718 and,instead of having its engaging end normally urged downward into positionto engage the shoulder 5'. of the adjacent detent, as is the case withall of the pawls 718 and 718, the engaging end of the pawl 718" isnormally urged upward to the position shown in Fig. 2, by a light spring718"". Arranged in the path .of movement of pin 718" is a cam finger 790 provided with an upper cam surface 791. This cam finger is normallyheld upward by "means of an arm 792 carried by a shaft 793, the arm 792being connected with the cam finger by means of a light spring 7 94which is attached to the arm 792 by means of a slotted connection, asshown, for a purpose which will appear. Arranged beneath cam finger 790in order to limit its lowest position is a stop 795. Attached to theouter end of shaft 7 93 isan operating lever 296, Fig. 1,.and to thislever is connected a key 297 which is projected upward through thekey-board in convenient position for operation, and normally held upwardby means of a spring 298. In operation at this point if a key 211 in abank in line with or to the left of the intermediate detent 717 (whichhas no tail d) be operated at will, upon operation of the operatinghandle cause the operation of detent 717 in line therewith, and all ofthe detents 717 to the right thereof until the detent 717 is reached,but this detent, because of the omission of its tail (5, does nottransfer to the next detent, so that only the hammers up to andincluding the hammer controlled by the detent 717 will be operated,unless, of course, a key in a bank to the right of the detent 718 hasbeen operated. The operation of the key last mentioned, causes theoperation of the detent 717 in line therewith by reason of the fact thatas the operating handle is moved, the carrier 611 relating to the bankof keys containing the operated key moves forward out of the line ofmovement of the rear end of the corresponding pawl 718*, and thuspermits this pawl to engage the alined detent 717 while all of the otherpawls 718 are thrown upward to the position occupied by the pawl 718 inFig. 4-by reason of the engagement of the rear ends of these pawls withthe shoulders ;I of thealined carriers 611, and the operation of thehammers 715 to the right. of the thus operated detent 717 is due to theaction of the overlapping tailsd'.

- Pivoted upon shaft 600 between the two carriers 611 which relaterespectively to the right-hand bank of the left-hand set of banks ofkeys, and the left-hand bank of the right-hand set of banks, is a plate695 provided with a pin 696 which extends over all of the carriers 611to the left of plate 695.

The plate 695 is provided at its lower end with a finger 697 which whenthe carriers 611 are in their lowest and normal position engages theforward or substantially vertical arm of the cam finger 790 and preventsit from dropping down into the path of movement of pin 718 If it isdesired to make the machine complete and cause a transfer, the operatordepresses key 297, whereupon shaft 7 93 is swung and arm. 792 moved tothe position shown in full lines in Figs. 2 and 4, whereupon the supportof spring 79 1 on the cam finger 790 is released, and the cam fingerwill then be entirely supported by the finger 697 of plate 695. With theparts in this position, so soon as the operating lever is moved, all ofthe carriers 611 move upward to the position shown in full lines in Fig.4, and dotted lines in Fig. 2, and when in this position, the finger 697will have moved to. the position shownin dotted lines in Fig. 2, thuspermitting the cam finger 7 90 to drop slightly, but not suflicient tobring its top below the center of pin 718 Continued movement of theoperating lever swings arm 711, and thus draws the pawls 718, 718 and718 to the right and brings all of the rear ends of the pawls 718 and718 into engage- .ment with the alined shoulders 51 If none of the keysof an of the keybanks have been operated, all of the pawls 718 and 718will have their free ends thrown upward by reason of engagement with theshoulders y, and none o f-the detents 717 and 717 will be engaged, andconsequently none of the hammers 715 will be operated, the pin 718" ofthe pawl 718 passing under the free end of the cam finger 7 90. If anyof the keys of the banks to the right of the split of the machine havebeen operated, the corresponding carriers 611 will be moved up out ofthe path of movement of the rear ends of the .alined pawls 718 and 718*,and the proper pawls will cause an engagement of the alined catches 717and consequent operation of the hammer 715, the action being exactly thesame as in the machine illustrated in the patent already referred to,the cam-finger 790- being held up above the path of movement of the pin718" by means of the plate 695. If, on the other hand, any one of thekeys of any of the banks corresponding to the carriers 611 over whichthe pin 696 of plate 695 extends, have been operated the correspondingcarrier 611 will be raised above its zero position, and will carry theplate 695 up far enough to retract finger 697 from cam-finger 790 andpermit it to drop upon the rest 795 with its forward end below thecenter of pin 718' so that when the pawls 718, 718 and 718" are moved tothe right, pin 718" will ride u over the cam 790, thus causing adepression of the free end of the pawl 718 and causing it to en gage itsdetent 717, and thus cause the release of the corresponding hammeroperating lever 716 and, by reason of the overlapping tails d of all ofthe detents to the right thereof, will cause the successive release andoperation of all of the hammers 715 to the right. \Vith the arm 792 inthe position shown in full lines in Figs. 2 and 4, therefore, themachine is capable of printing the intermediate zeros in a number equalin points to the total number of banks of keys. At any time, however, byswinging arm 92 to the position shown in dotted lines in Flg. 2, andthus supporting the cam-finger 790 out of the path of movement of the pm718" the machine may be split so as to enable the operator to writesimultaneously two or more independent columns of numbers.

As hereinbefore referred to the arm 792 has an elongated slot in whichthe lower end of the spring 794 is loosely secured in such manner as toafiord a little play between such arm and the spring. This arrangementis desirablein order that the spring shallnot resist the action of theplate 695 in lifting the finger 790 when such action is requiredinasmuch as, in such event, the end of the spring slides freely in theslot which would-not be the case if the opening in the arm 792 was notelongated. Moreover the spring constitutes a link between the cam'790and the arm 792, such link being preferably flexible instead ofa rigidlink -for. if such latter link were used and the shaft 793 should bemoved by the connectinglmechanism during the time the parts are in theposition illustrated in Fig. 4, it might result in an injury to'themechanism, owing to the pull of the arm 792 upon the cam finger 7 90tending to throw its rearward end upwardly while under the pin 718 1With the present construction, however, the spring 794 would, in suchevent, simply be elongated and the finger 7 90 would rise to itselevated position on the return of the parts to their normal position.

It will readily occur to any -one skilled in this type of machines thatmany modifications of the construction just described may be madewithout departing 32m the spirit of my invention. In Figs. 5 and 6, Ihave shownrone of these modifications. In this construction, none of thepawls; 718 are changed, but instead for the detent 7 17 which wouldordinarily aline with the righthand bank of keys at the line ofsplitting of the machine, I substitute a detent 717 which, instead ofbeing provided with a tail d overhanging the next adjacent detent 717,

is provided with a sliding finger 717 which is normally urged out ofalinement with the heel d of the next adjacent detent 717 by means ofthe light spring 717. The finger 717 is preferabl carried by a slidingcarriage 717 rovi ed at its outer end with a. pin 717 a apted to beengaged b one arm of a lever 7 90 which is connecte and slot connectionwith an arm 7 92 carried by the shaft 793. The detent 717 is thenprovided upon its left-hand side with a shoulder 717 over which the taild ofthe detent 717 to the left will project. The operation of thismodification is readily apparent. With the parts in position shown infull lines in Figs. 5 and 6, an operation of the detent 717 either bydirect engage ment by its own pawl 718, or by receiving actuation fromthe taild of the detent 717 to its left, will not affect the detent 717to its right, for the reason that its pin 717 will not engage the heel0Z thereof. If, however, the parts be moved to the positions shown indotted lines in Fig. 5, pin 717 will automatically transfer to thedetent 717 at its right.

It will be readily understood that the mechanism for splitting andcombining the machine may be operated automatically, either bysuccessive movements of the operating lever, or by the operation of themovable paper carriage, without departing from my invention. In Figs. 7and8 I have shown means for automatically operating the mechanism by amovable paper carriage. Here the shaft 793 is provided with a lever 50connected by a'link 52 with a lever 54, this last-mentioned lever 54having an arm 54 extended into the path of'movement of a cam 55adjustably arranged on a longitudinally slotted plate 55 mounted uponthe paper carriage 56: In this construction, the carriage carries a rockshaft 57 provided with a pawl 58 adapted to engage in any one of theseries of notches formed in the stationary bar 59, whereby the carriagemay be 'held in different columnar positions. Shaft 57 also carries oneor more arms 60 which may be adjusted either in alinement with or inposition to be brought into alinement with a pawl 61 carried by a lever62, which lever is operated upon each operation of the main operatinglever by means of a lever 63, the arrangement being such that, upon eachcomplete swing of the lever 63,

the catch 58 will be withdrawn from one of the notches of bar 59, andthen permitted to be returned in engagement with the next notch ofthe'bar 59 as the carriage is automatically shifted by the spring drum64.

It will thus be understood that the mechanism which controls the splitor combined chine when such column is printed.

or whether t e machine is complete and capable of operation as anentirety. Moreover the arrangement is such that said mechanism may bemoved or operated by the movable paper carriage at any particularposition of the latter as predetermined by the operator, With the resultthat the machine may be automatically split or left complete accordingto the position of the paper carriage and according to any predeterminedplan of the operator, under which arrangement some columns on a sheetof'paper may represent the work of the complete machine and othercolumns may represent the work of themachine as split, the position ofthe carriage and consequently of the particular column with relation tothe printing mechanism determining the particular condition of the ma-Thus when the carriage is in the particular position illustrated in Fig.7, the arm or finger 54 which extends rearwardly in position to beoperated upon by a projecting portion of the movable paper carriage, isin its inactive position but is interposed in the path of movement ofthe cam and is arranged to be rocked downwardly by such cam when thelatter is presented thereto. Inasmuch as the arm or finger 54 is ininactive position and as the normal condition of the machine is split,the machine is of course at this time ,When the paper carriage advancesto the next columnar position, thereby carrying the cam beyond the armor finger 54, the parts will be restored to the relative positionindicated in Fig. 7 with the exception that such arm will be on theother side of the cam 55. The machine is now again in split condition.By adjustably mounting the cam 55 in the slotted plate 55 as beforementioned, the machine may be rendered split or cgmplete for thedifferent columns on a sheet of paper as determined by location of thecam. In this manner different characters of accountant work may bereadily provided for so that the machine may be split or completeaccording to the particular position of the paper carriage and withoutany attention on the part of the operator.

The machine thus far described is de signed to enable the operator towrite upon the same page several columns of numbers. With such amachine, it is convenient to provide means for preventing the operationof the accumulator at times, and the apparatus already described maytherefore,'

e combined with some means or controlling the accomplishment of functionof the accumulator. If desired, mechanism such as hereinafter described,may be used,. or any other suitable mechanism for controlling theaccomplishment of function of the accumulator. In the present drawings Iindicate briefly the means for shifting the accumulator which means perse form no part of my present invention.

The lever 54, (Fig. 1) exactly like lever 54 shown in Fig. 7, isconnected by a link 54 to a lever 54 pivoted upon shaft 600. Lever 54 isprovided at one end with a fin- 'ger 54 adapted to engage a pin 828'carried. by. latch 828 and thus prevent it from .sition, to be engagedby a lug 813' carried by lever 813, and to then engage a lever pivotedon shaft 800. The lever 65 is provided at its upper end with a notchwhich receives a pin 226 carried by link 226.

In operation, the lever 54 is normally held in the position shown infull lines in Fig. 1 by a spring 54. When lever 813 is moved to the leftits lug 813 engages pin 54 and drives it against lever 65, whereuponlink 226 pulls upon lever 227 which drops and permits link 911 and link914 to drop until the upper rear edge of notch 914 drops below thecenter of pin 910'. and link 914 is pulled by the spring 911 away frompin 910 and thus leaves the accumulator 916 out of accumulatingposition. By depressing the left-hand end of lever 54" by cam 55 pin 54is withdrawn from between lug 913' and lever 65 so that the function oflink 914, and consequently of the accumulator is not interfered with.Thus the accumulating mechanism is under the control of the papercarriage whose-position determines whether such mechanism is operativeor inoperative. According to the construction shown in Fig. 1 thecontrolling mechanism, that is the lever 54" and its associated parts,is in position to normally interfere with the accumulating mechanism andrender the same inoperative inasmuch as normally the pin 54 is in aposition to form an operating connection between the block or lug 813andthe substantially ver tical lever 65, with the result that when themachine is operated with the controlling mechanism in normal condition,the lever 65 will be rocked rearwardly and the link 226 moved rearwardlyand the total key bell crank 227 rocked downwardly slightly so as toplace, through the medium of the l nk 911, the pitman or link 914 in aninoperative position, which is intermediate 1ts normal or its upperposition as shown in F1 1 and its lower depressed 1n the operation oftaking a total. When the itman or' link is in such intermediateposition, it can no longer control the swinging of the accumulatorpinions 1n the manner hereinbefore explained, but after such pinionshave been swung forwardly out of mesh with their racks upon the initialor forward stroke of the operating handle, such pinions are left out ofme'sh'upon the return stroke is inasmuch as the pitinan 914 which hasheretofore served to so return them upon the rearward or return strokeof the operating handle is in its inoperative or intermediate position.The result is that the racks 610 descend and then ascend while theaccumulator pinions are out of mesh, with the result that the movementsof such racks-or sectors are not transferred to the accumulator pinions,or in other words, the accumulating mechanism is at this time 1nregularstandard Burroughs machine inas-- much as the rocking of the lever 813will have no effect whatever upon the lever so that the accumulatorpinions will be controlled by the itman or link 914 in the usual andwellown way. Therefore in this particular position of the paper carriagethe accumulating mechanism will be in operative condition and the itemsin the particular column vnow being listed will be accumulated by themachine; The rovision of a plurality of cams 55- and their adjustment orlocation in the slotted plate 55, in the manner hereinbefore explained,will permit different columns of items to beprinted on the same sheet ofpaper some of which columns represent accumulated items and others itemswhich have simply been printed without accumulation, the order andarrangement of the accumulated and .non-accumulated columns beingaccordin to the prearran ed plan of the cams 55. It is understood oweverthat the feature of so controlling the accumulating mechanism does not,per se, form any part of my present invention inasmuch as I have made itthe subj ect matter of an application heretofore filed by me (Ma 12,1904, Serial No. 207,631, now Patent No. 1,028,133 issued June 4,

osition to which it is shifted or I 1912), and I herein claim thisfeature only as an element in some of the claims, in a combinationincluding the means for controlling the split and complete conditions ofthe machine whereby a number of columns of items may be simultaneouslyprinted with a single machine and whereby the machine may print some ofthe columns on the sheet of paper without accumulating the itemsthereof. 4
